That syntax is very clean when it works. I think however the limitation of not being able to pipe arguments into 2nd, 3rd, ..., positions and keyword arguments, or variadic explosion like the syntax showcased in the article makes it less powerful.

Are there other syntax helpers in that language to overcome this?

It still makes sense to have a clean syntax for the simple case. You can use currying (with or without first class language support) to handle more complex cases or just fall back to good old function composition or even loops.
